There are two types of Mac users: the mouse-centric, the keyboard jockeys, and those who refuse to sleep with Windows users. OK, three types.
This tip is for users like me whose knowledge of each application's set of keyboard shortcuts is prodigious. Even we get stumped occasionally when a shortcut doesn't work as expected or is simply missing. This is very easily remedied.
In the Keyboard & Mouse preference pane in System Preferences, you'll see a little "+". Click it, identify the application you're after and type the name of your target menu item. Next, simply pick a shortcut, click "Add" and you're done! You shortcut is in place and you can avoid another time consuming journey from your home keys to your mouse.
